Filter Keys is not a function of your specific keyboard; rather it is a feature of Windows.

FilterKeys is a keyboard feature that instructs the keyboard to ignore brief or repeated keystrokes.
--Using FilterKeys, you can also slow the rate at which a key repeats when you hold it down.

To turn off FilterKeys, clear the Use FilterKeys check box.
1.Open Accessibility Options.
2.On the Keyboard tab, under FilterKeys, clear the Use FilterKeys check box.

it is only for a computer keyboard hope it help from you.

A computer keyboard serves as a main operating tool for accessing and inputting data into a computer. The keyboard features many functions and keys that a user may never use, but is still essential to some users. Understanding the keyboard can improve computer knowledge and use.

QWERTY Pad

The "QWERTY" pad is main sections of letters on the keyboard. These letters are mainly used for typing and also as shortcuts in programs like Windows Movie Maker, Adobe After Effects and computer games.
Number Pads

The far right side of the keyboard features a number pad that resembles a calculator. This number pad is essential for programs like Excel, but can also be used to input numbers as a typing function. More numbers are just above the "QWERTY" keyboard that also feature symbols when the "Shift" button is used.
Arrow Keys

The right bottom of a keyboard features four directional arrow keys. These keys provide navigation through word processing documents and also serve as scrolling functions in web browsers.
F Bar

The top of a keyboard features the "F Keys," a selection of keys that extends to "F12" on most keyboards. These keys serve different functions. For example, "Alt and F4" exits out of a program. "F1" will start the typing helper in word processing programs.
Extra Keys

New keyboard feature shortcut keys at the top of the keyboard. These include shortcuts like "Power," "Sleep Mode," "Calculator," "My Computer" and "Web." Some also include media controls for movies and music.

To access the calculater, go to the start menu, and in the search box at the bottom, type "calulator". It will appear in the list above. Click it, and it will open.
To use the number pad on the keyboard (if equipped) make sure the "num lock" is on, on the keyboard. (usually directly above the 7 button).
For different uses, such as scientific and that, there should be a file menu on the calculator that will allow you to switch between various forms of the calculator.

You might have enabled the Windows "Accessibility" features, i.e., instead of pressing CTRL-ALT-DELETE at the *SAME* time, you can press CTRL, release it, press ALT, release IT, press DELETE, release it, to emulate the three-finger salute.

Reboot your computer, to start without the "Accessibility" feature active.

Also, try a different keyboard.
And try the keyboard in a different computer.

The keyboard and the mouse work on different wireless sensors. Your wireless keyboard should have come with a receiver too. Unless the mouse and keyboard came together as a set, you'll need two different receivers. Check the battery compartment of the keyboard for the sensor. Some models have a hidden area there to store the usb key for the keyboard.
The only exception is if the keyboard is bluetooth, and your computer already has a bluetooth receiver in it (many laptops and phones come with this feature, lately). You will have to check the website for your keyboard's manufacturer to download drivers. You may also be able to order a replacement USB key for it, but I've never been able to. :P
Best bet is to contact the guy you bought the keyboard from and ask him/her: "Where's the USB receiver for this keyboard you sold me?"

You probably need to unlock some features in career mode or campaign, something to that effect.

Or just look up cheat codes

The problem may be two things:

1) Its cord is disconnected from the PC unit
2) Your Keyboard drivers are outdated.

If the cord is fine, I recommend that you go to the hardware wizard (Start Menu -> Settings -> Control Panel -> Hardware Wizard) and run a "detect new hardware." This feature should be able to get your keyboard going again - and you should be able to access this feature by using your mouse only.

I have the Microsoft Comfort Keyboard and it has a "F lock" key. This key has to be set on "Off" to let it know that I want to use the Print Screen function versus the Insert function on the same key. May be your keyboard is the same way.

The button puts your computer in to standby. If you do not want this to happen, you can turn that feature off from within your Keyboard Software.
